GAS-REGULATOR.

SPECIFICATION forming part of Letters Patent No. 713,856, dated November 18, 1902. Application filed March 27, 1902. Serial No. 100,225. (No model.)

To all whom, it may concern.-

Be it known that I, MELVIN D. COMPTON, a citizen of the United States, and a resident of East Orange, in the county of Essex and State of New Jersey, have invented certain new and useful Improvements in Gas-Regulators, of which the following is a specification.

My invention relates to gas-regulators, more especially to the class known as pressure-regulators.

The object of the invention is to furnish a compact, efficient, and cheap device for regulating the gas-pressureone that occupies small space and whose accurately-controlled regulating mechanism is easily accessible.

To this end I have invented the device shown in the drawing hereto attached, in which a'vertical cross-section is shown, the regulator being circular in shape.

Referring to the drawing, A is the body of the device, provided with a screw-furnished gas-inlet B and a screw-furnished outlet B.

O is the cover; D,the bottom, represented as attached by screws.

E is a flexible diaphragm, on the upper side of which is placed a predetermined weight F.

G is a cone-shaped valve controlling the aperture K, leading into the chamber G.

H is a spiral spring fitting into a cylinder formed integral with the valve G. The tension of the spring H is controlled by the screw J, having a reduced end portion 7', so as to form on the screw J a shoulderagainst which the spiral springH abuts. I denotes guides, here represented as pins for controlling the vertical movements of the valve G.

The operation is as follows: The flexibility of the diaphragm E and the weight F is so proportioned that with a given pressure of gas and without the spring H acting the opening K of the valve-seat is a maximum.

The gas then enters at B, follows the course ofthe arrows through the aperture K, the chamber G, and out through B. It is evident that any variation of the gas above what the diaphragm E is loaded for will act upon the under side of the diaphragm, raise it, and thus control the aperture K, checking the flow of gas until the momentarily too great pressure ceases. In order to make my adjustment, however, more delicate and assure control within any desired limits, I have provided my conical valve, as shown, with a hollow-cylinder attachment, into which fits the spiral spring H. I now turn the screw J to act upon the spring, thereby relieving a portion of the weight on the loaded diaphragm E, when it is evident that a slighter variation of pressure will control the diaphragm E and with it the attached valve G, and this can be brought to any degree of delicacy required.

By loading my diaphragm with a predetermined weight I accomplish two objectsfirst, I obviate the necessity of removing the top O to add to or take away weight, thereby enabling me to attach permanently my device in places where the top might not be conveniently accessible, and, second, Iam enabled by means of my screw-controlled upwardly-acting spring, which is easily accessible to the screw-driver, to much more accurately gage the weighted diaphragm, and

consequently the valve-aperture K.

Having thus fully described and illustrated my invention, what I claim is- 1. In a gas-regulator, a casing having inlet and outlet ports therein, a downwardly-facing valve-seat between said ports, a conical valve cooperating with said seat for controlling the passage between said ports, a diaphragm above the valve-seat, a fixed weight on said diaphragm acting to normally maintain said valve in its depressed open position, a hollow cylindrical extension on the under side of said valve, a coil-spring within said extension, and an adjusting-screw in the bottom of the casing, said screw being reduced at its upper end to form a shoulder on which the lower end of the spring rests, substantially as and for the purpose specified.

2. In agas-regulator, a casing having inlet and outlet ports therein, a diaphragm in said casing, a valve pendent from and connected thereto for controlling the passage between said ports, a fixed Weight on said diaphragm for normally maintaining said valve in its open position, a spring within the casing acting upon the under side of said valve in opposition to said Weight, and means outside the casing for adjusting the tension of said spring.

3. In a gas-regulator, a casing having inlet and outlet ports therein, a diaphragm in said casing, a valve pendent from and connected thereto for controlling the passage between said ports, a fixed weight acting upon the upper side of said valve for normally maintaining the same in its open position, an adjustable spring acting on the under side thereof in opposition to said Weight, and a guide for said valve in its movements toward and away from its seat.

4. In agas-regulator, a casing having inlet and outlet ports therein, a diaphragm in said casing, a valve connected thereto for controlling the passage between said ports, a fixed weight acting upon said valve for normally maintaining the same in its open position, an adjustable spring acting thereon in opp0sition to said weight, a cylindrical extension on said valve, and guide-pins on said casing within which said extension moves.

5. In a gas-regulator, a casing having inlet and outlet ports therein, a downwardly-facing valve-seat between said ports, a conical valve cooperating with said seat for controlling the passage between said ports, a diaphragm above said ports from which said valve is suspended, a fixed weight on said diaphragm acting to normally maintain said valve in its depressed open position, a hollow cylindrical extension on said valve depending from the center thereof, a coil-spring within said extension, and an adjusting-screw in said casing acting upon the lower end of said spring, as and for the purpose set forth.
